Specification of Letters Patent.

\ A pli ation filed November 29, 1904. Serial No. 234,707.

To all whom it may concern:

Be it known that I, GEORGEPLANTA BARNES, engineer, a subject of the Kingof Great Britain and Ireland, residing in Brornley, countyof Kent,England, have invented certain new and useful Improvements in andRelating to Apparatus for Spraying Liquids, of which the following is aspecification.

This invention relates to apparatus for spraying liquids, and has forits object to provide a simple and eflicient means for spraying liquidsand one which can be readily adjusted, will be reliable in use, and maybe used I in almost any liquid Without the orifices bemy invention andcoming clogged.

Apparatus for spraying liquids made in accordance with my inventioncomprises a trough or receptacle in which the liquid is disposed, anozzle having two or more duets with apertures of the same or ofdifferent sizes disposed at or near the surface of the liquid, the saidducts or apertures being at an angle to each other andone or both at anangle to the liquid to-be sprayed and through which ducts or apertures ablast of steam, air, or other vapor acts upon the liquid outside tospray or spread the same.

Referring now to the drawings, Figure 1 isi a front elevatlon, partly 1nsection.

Fig. Qis a plan of same. Fig. 3 is a sectional .side elevation, and Fig.i a section of a modified form of apparatus made in accordance with myinvention. Figs. 5 and 6 are sectional views of two forms of nozzle madein accordance with the liquid.

In the form of apparatus shown in Figs. 1, 2, and 3 and adapted for usein damping or spraying webs of paper or other materials in themanufacture or in the subsequent use thereof I employ a trough a,disposed in a 7 or bar d, upon which are mounted brackets or guides e,having adjustable carriers f f thereon. At the back of the trough andparallel with the frame wis a compressed-air-supply pipe 9, havingseveral branches 7a 7b, which terminate in nozzles j j. The nozzles areadapted to rest in and be supported by the cartheir position in relationto riersf, each nozzle or pair of orsection of nozzles being capable ofbeing regulated as toward the liquid independently of the others byscrewed handles is, working between the carrier 3 and thebracket e. Theframe or bar d is adapted to, be raised by cams m for the purpose ofraising or adjusting the level of all the nozzles simultaneously. Thenozzles jjare preferably provided with two holes "97/ 0, inclined to oneanother, and I find that an ordinary gas-burner having two orificesinclined to one another, as shown in Fig. 5, well suited forsomepurposes, while forother purposes best results are obtained byhaving the upper hole parallel, or nearly so, with the liquid in thetrough, the lower hole being at an angle thereto, as shown in Fig. 6.

In use for damping webs of paper or other materials the trough a isfirst filled from the running-tap bwith water or other liquid to besprayed until it overflows at c. The nozzles j j are then separatelyadjusted, preferably so that the lower hole 0 is slightly below or-on alevel with or sufficiently near the surface of the liquid, the otherhole a being close to and directly above it, that when the blast isapplied the liquid outside the hole o of each nozzle is by the combinedinfluences of suction and capillary attraction lifted and partly brokenup, to be still further broken up by the blast coming through the holeor holes above, and the fine spray is blown out over the edge of thetrough ontothe web.

In some cases the holes a and 0 may be duplicated. The frame or bar cl,carrying the nozzles 7' can then be raised or lowered, ac-

cording as it is desired to adjust the volume of the liquid in thespray, or this result may be obtained by raising or lowering theoverflow-pipe 0, thus dispensing with the sliding bar 01 and the cams m,the nozzles in this case being fixed at an exact level as to the liquid.

The branch pipes h it maybe partly made of rubber or other flexible hoseto permit of each nozzle being raised or lowered, or in.

some cases the supply-pipe g may be pivoted or the branch pipes it itprovided with flexible "joints for the same purpose.

WV hen used for the purpose of spraying liquid fuel, the same form ofnozzles and orifices are used, the supply of liquid to each nozzle orpair or sections of nozzles being through an independent pipe, such asall connected, however, outside the'furnace to a general supply ofliquid kept at a desired level. In the case of furnaces liable tomovement, such as in ships or trains, the pipes and nozzles, togetherwith the general supply of liquid for the nozzles, are governedautomatically so as to spray the liquid from each nozzle withoutvariation in quantity.

What Iclaim, and desire to secure by Letters Patent, is-

1. In apparatus for spraying liquids, the combination of a plurality ofducts adapted for connection to afluid-compressor, a plurality of saidduets being inclined toward acommon point, a chamber adapted to containthe liquid to be sprayed, the ducts being disposed in such a positionwith relation to the surface of the liquid in the chamber that theliquid is raised from said chamber and sprayed without passing throughany ducts, substantially as described.

2. In apparatus for spraying liquids, the combination of apressure-fluid-supply pipe, a nozzle at the end of said supply-pipe, aplurality of orifices in said nozzle and inclined to one another, achamber adapted to contain the liquid to be sprayed, the nozzle beingdisposed in such a position that the liquid is sprayed Without passingthrough the nozzle, substantially as described.

3. In apparatus for spraying liquids, the combination of apressure-fluid-supply pipe adapted for connection to a fluid-compressor,a nozzle at the end of said supply-pipe, a plurality of orifices in saidnozzle and inclined to one another, a chamber adapted to contain theliquid to be sprayed, and means for adjusting the relative positions ofthe nozzle and the liquid so that the liquid is sprayed without passingthrough the nozzle, substantially as described.

4. In apparatus for spraying liquids, the combination of a fluid-supplypipe adapted for connection to a fluid-compressor, a nozzle at the endof said fluid-supply pipe, a plurality of orifices in said nozzle andinclined to one another, a chainber adapted to contain liquid, and meansfor adjusting the relative positions of the nozzle and the liquid,substantially as described.
